Abstract null null The goal of this study is to investigate the wire + arc additive manufacturing (WAAM) of a high-entropy alloy (HEA) and to identify the near-optimal process parameters. To achieve the goal, a two-stage investigation is attempted using pre-alloyed and extruded Al0.1CoCrFeNi wire. In the first stage, single-layer beads are deposited with a range of process parameters (current, wire feed speed, and travel speed). Through process-signal monitoring, bead cross-section measurements,...

Abstract Bimetallic additively manufactured structures (BAMSs) can replace traditionally-fabricated functionally-graded-components through fusion welding processes and can eliminate locally-deteriorated mechanical properties arising from post-processing. The present work fabricates a BAMS by sequentially depositing the austenitic stainless-steel and Inconel625 using a gas-metal-arc-welding (GMAW)-based wire + arc additive manufacturing (WAAM) system. Elemental mapping shows a smooth compositiona...

This chapter presents an innovative framework for the application of machine learning and data analytics for the identification of alloys or composites exhibiting certain desired properties of interest. The main focus is on alloys and composites with large composition spaces for structural materials. Such alloys or composites are referred to as high-entropy materials (HEMs) and are here presented primarily in context of structural applications. For each output property of interest, the correspon...

Abstract To obtain Al alloys possessing the excellent hydrogen-generation performance with high efficiency/low cost via the hydrolysis reaction of aluminum with water, a series of as-cast Al alloys (∼10 g) alloying by 13 kinds of Ga-based low melting point alloys with different contents were prepared by the high frequency induction melting method under a high purity argon atmosphere. The effect of the content and composition of the low melting point alloys on the hydrogen-production property of ...

High-entropy alloys (HEAs) have become a research hotspot in recent years. The nature of the multi-principal elements, high mixing entropy, and mutual interactions between elements render this novel material outstanding mechanical and functional properties, in which most research efforts are focused on mechanical properties. There are many aspects that can influence the mechanical behavior, such as constituent elements and fabrication methods. This paper will mainly summarize and discuss the eff...

The basic principle of high-entropy alloys (HEAs) is that high mixing entropies of solid-solution phases enhance the phase stability, which renders us a new strategy on alloy design. The current research of HEAs mostly emphasizes mechanical behavior at room and higher temperatures. Relatively fewer papers are focused on low-temperature behaviors, below room temperature. However, based on the published papers, we can find that the low-temperature properties of HEAs are generally excellent. The gr...
